IEA slashes Russian oil output forecast as Ukrainian drone strikes take their toll

The International Energy Agency just took a red pen to its Russian oil forecasts, and the numbers tell a story that Moscow would probably prefer to keep quiet. The IEA cut its 2026 Russian crude production outlook by 200,000 barrels per day, bringing the revised estimate down to 8.95 million bpd.

The reason is straightforward: Ukrainian drones keep hitting Russian energy infrastructure, and the damage is adding up faster than repairs can keep pace.

Six months of decline and counting

Russian crude output in May 2026 clocked in at just 8.7 million bpd. That’s roughly 5% lower than the same period last year and a full 10% below Russia’s stated monthly production target.

This isn’t a one-month blip. Russian oil production has now declined for six consecutive months, shedding approximately 370,000 bpd from its November 2025 peak.

Ukraine has doubled its attacks on Russian refineries and production facilities since the start of 2026. The campaign has evolved too, with longer-range drones now reaching more remote production areas that were previously considered safe from the front lines. Full and partial shutdowns across various refineries and facilities have become a recurring headache for Russian energy planners.

Russia itself acknowledged the production slide publicly for the first time in June 2026. The official explanation pointed to “unexpected maintenance issues.”

The export puzzle

Despite the steady erosion of production capacity, Russian crude and product exports have held remarkably steady at about 7.4 million bpd on a year-over-year basis.

Russia is producing less oil but shipping roughly the same amount overseas. The math only works if domestic consumption is absorbing the hit, or if Russia is drawing down inventories to maintain export volumes. For a country whose federal budget is deeply dependent on oil revenue, maintaining export flows makes perfect strategic sense even at the cost of domestic reserves. Buyers in India, China, and elsewhere have been happy to keep purchasing Russian crude at discounted prices since the early days of the Ukraine conflict.

What this means for energy markets

Traders watching oil futures should note the gap between Russia’s actual May output of 8.7 million bpd and the IEA’s full-year forecast of 8.95 million bpd. That gap implies the IEA expects some production recovery in the second half of 2026, which is an optimistic assumption given that Ukrainian drone capabilities appear to be expanding, not contracting.
